Forced to choose between loyalty to the homeland and loyalty to the tribe, Jews have traditionally chosen treason. This is the poison pill of anti-Zionism, for it throws the Jews back into the Diaspora where they may revert back to their normal treacherous role. On the other hand, Zionism has not solved the problem of Jewish disloyalty and dual loyalty. In fact, it has worsened it by orders of magnitude. Whereas before Zionism Jews may have been mildly treasonous, afterwards Jewish treason went through the roof as Jews captured nation after nation throughout the West and turned one White country after another into a colony of Israel.
All things considered, I think Jews would be much less treasonous without a Jewish state.
So yes, the dismantling of Zionism would throw the Jews back into the Diaspora and bring back the boogeyman of Jewish dual loyalty. But Zionism has morphed the dual loyalty monster into a titan. All in all, I feel that Jewish dual loyalty would radically diminish if the Jews no longer had a state that they could use to drag generations of White Gentiles into fighting and dying for them in the endless Wars for the Jews we see playing out across the land, in Iraq, then in Libya, next in Yemen and now in Syria and soon to be Iran. Lebanon? Been there, done that. 323 Marines died in that War for the Jews.
